Causes. The infectious diseases are often transmitted by pathogens. NCDs or non-communicable diseases are those conditions that are usually not passed on from one affected person to others, but are caused as a direct result of lifestyle and environmental factors. Knowledge of the factors underlying disease emergence can help focus resources on the key situations and areas worldwide (3,4) and develop more effective prevention strategies. Yet, probably at least 2000 years before Western medicine discovered bacteria and viruses, Chinese medicine developed a strategy for diagnosing and treating the illnesses bugs caused - even though doctors didn't know the bugs existed! COPD Risk Factors. Natural (Biological) Causes Selective Pressure. The web of causation offers a useful way forward in understanding aetiology and linking social determinants and social factors and biomedical aetiological factors. The complete pie, which might be considered a causal pathway, is called a sufficient cause. 3. intrinsic determinants. What causes chronic diseases? The causes of disease. Predisposing factor may create a state of susceptibility of disease to host. 4. extrinsic determinants. e.g. Smoking is the biggest risk factor for chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema.

Epidemiological theory is not applicable for non infectious and chronic diseases like coronary artery diseases etc. These are age, sex and previous illnesses. The idea that disease etiology and distribution are attributable to causes deemed "far" from and "near" (including within) the body is ancient22 - 27; Hippocratic tradition, in the 5th century BCE, famously invoked both atmosphere and individual constitution as explanations for epidemic disease.22, 25 By contrast, the idea that there is a .
